ED4 Surge Arrestor 

Electrical District No 4 is happy to announce that we are now offering the purchase and installation of secondary surge arresters.

The following will be required before installation can occur:

  • You, the customer, will need approval for the installation from your HOA and ED4 will require a copy of this approval.

  • A signed agreement between ED4 and the customer for the purchase and installation of the Surge Arrester.

  • An inspection of the external grounding system at the customers property will be performed at the time of installation.

  • Payment of the Surge Arrester and installation will need to be paid before installation can be scheduled. Charges may vary and are typically under $100.00

ED4 has set aside Thursdays for the installation of the surge arresters. Scheduling can be made after all requirements have been met.
